WebBy definition, the optical flow is the vector field (u, v) verifying image1 (x+u, y+v) = image0 (x, y), where (image0, image1) is a couple of consecutive 2D frames from a sequence. This … Weblines in the image. 1. Introduction Optical flow is the distribution of apparent velocities of movement of bright- ness patterns in an image. Optical flow can arise from relative motion of objects and the viewer [6, 71. Consequently. optical flow can give important . information about the spatial arrangement of the objects viewed and the rate
